analyze disk space usage
SpaceSniffer analyzes a selected hard drive and presents you with a dynamic disk map that makes it easy to spot files and folder that take up most of your space. You can review the map in real-time while the application is scanning, and any changes made (e.g file deletions, renames, new files added) during the scan are automatically reflected without the need to rescan. Right-clicking on a file or folder brings up the standard Windows Explorer context menu. Other features include folder tagging, folder name filtering, custom file classes (define your own colors for file groups), support for NTFS Alternate Data Streams, folder zoom and more. Portable, no installation required.

I've been using other space and size viewers but I must say, I am very happy with this one. It's one of the easiest to view and navigate through. There are plenty of viewing options, size of windows, detail, color, etc... Yep, I think this is a keeper.

Of all the disk usage utilities I have tried, Space Sniffer is the best. The display is easy to understand and you can delete things from the display area, there is no need to navigate using some other method. It is portable, too, and now lives on my handy-dandy fix-the-family's-computer USB stick. A great diagnostic tool to have in your arsenal.
